The properties of a substance depend on what atoms are present and how those atoms are bonded (held together). For high school Chemistry, you need to know about three types of chemical bonding - ionic, covalent and metallic. This quiz is all about ionic bonding which combines metal and non-metal atoms and produces materials with high melting and boiling points which are usually soluble in water and made from giant lattices of ions that will conduct electricity if they are molten or dissolved in water.

1.
Pick the correct combination for the properties of ionic compounds.
Conduct electricity
Low boiling point
Do not conduct electricity when dissolved or molten
High melting point
Conduct electricity when dissolved or molten
High melting point
Do not conduct electricity
Low melting point
This is because ionic compounds are normally formed from giant lattices of ions
2.
When a non-metal atom becomes a non-metal ion...
it becomes negatively charged
it becomes neutrally charged
it doesn't change its charge
it becomes positively charged
Non-metal atoms gain electrons so there are more electrons than protons resulting in an overall negative charge on the newly formed ion
3.
The ionic bonds that exist between charged particles result in an arrangement that is called...
a giant ion
an ionic structure
a giant covalent structure
a giant structure
There are no limits to the size of a giant ionic lattice other than the number of ions available
4.
When an atom loses or gains electrons, it becomes...
an electrolyte
a bond
a compound
an ion
In an atom, the number of protons equals the number of electrons so the charges are balanced. When electrons are lost or gained, this is no longer the case
5.
Ionic bonding usually occurs between what type of atoms?
Metal and metal
Non-metal and non-metal
Metal and non-metal
Metal and noble gas
Two metals joining together form an alloy with metallic bonding, two non-metals will form covalent bonds and, at high school level, noble gasses are regarded as being inert
6.
How many ionic bonds are formed when magnesium combines with chlorine?
1
2
3
4
Magnesium has 2 outermost electrons, but chlorine atoms can only gain one electron during ionic bonding. The magnesium atom can therefore transfer electrons to two chlorine atoms i.e. two ionic bonds
7.
What happens to the electron configuration of the atoms?
The electron configuration becomes that of a noble gas
The electron configuration always loses one electron
The electron configuration always gains an electron
The electron configuration stays the same
If sodium 2,8,1 loses an electron in an ionic bond, its configuration becomes 2,8 which is the same as neon. Elements that have full outer shells of electrons are stable
8.
How many ionic bonds are formed when sodium bonds with chlorine?
1
2
3
4
One sodium ion combines with one chloride ion to become sodium chloride because only one electron is transferred
9.
When a metal atom becomes a metal ion...
it becomes negatively charged
it becomes neutrally charged
it doesn't change its charge
it becomes positively charged
Metal atoms lose electrons so there are more protons than electrons resulting in an overall positive charge on the newly formed ion
10.
How are electrons involved in ionic bonding?
Electrons are shared between the atoms involved
Electrons are lost or gained by the atoms
Electrons are taken into an inner shell of one of the atoms
Electrons are all moved to the outer shell of the atoms
Electrons are transferred between the atoms
